I've played this game through several times and have 'won' in normal mode using all the different races available at Armor Games. If ya like the game, you ought to 'stick it out' using three different races until The Arnolds become available. Playing with this 'team' is truly a HOOT and, once you 'master' their capabilities, is loads of fun!!
A few words of 'free' advice when using The Arnolds .
1. When you start the game, do not upgrade any unit until you have added the Submachinegunner (700), the Minigunner (1100) and the HK Drone (1700).
2. Once you have the submachinegunner, select a new engagement, generate five-or-six Halberdiers and then one-or-two submachingunners. The smg's are faster then the 'grunts' and will catch up and intermingle with them to provide extra firepower.
3. Once you get the Minigunner, select an engagement and start off with the two-or-three Halberdiers, followed by the long-ranged Minigunner, four-or-five Halberdiers, and then two-or-three Submachinegunners.
4. Once you get the Drone, sieges are a no-brainier breeze. Cannot imagine ever losing a siege with the Drones.
Anywise, this is a very good game with lots of re-playability.
